The climate is changing, now it’s undeniable, and we're seeing heat and cold waves, extreme events, rains that come in a flash and cause floods, plants that bloom out of season, and more.
But what happens when the climate makes life unbearable, so unbearable that you can no longer live? The only solution is to seek fortune elsewhere, hoping for an acceptable climate and to find a good job that allows a decent life. So many people are forced to leave home, memories and affections to escape the intemperance of the climate and if we do nothing to stop greenhouse gas emissions there could be many in the future.
In 2020, experts say, the number of people displaced by climate change set a new record, matching the steady increase that has been recorded over the past decade. The dynamics that force people to leave their homes are mainly related to the extreme phenomena caused by climate change, such as storms, floods and increasingly intense and frequent heat waves.
The data were published by the Norwegian Internal Displacement Monitoring Centre, according to which in 2020 (the hottest year ever recorded for the planet) 5 million more people were displaced than in 2019. The advancing desertification that makes it impossible to cultivate or raise animals and the erosion of the land leads the inhabitants to flee, to seek better living conditions.
And this will also affect the possibility of finding food. Indeed, according to the latest studies, the two are closely related. "The destruction of natural environments cancels the distance between wildlife and humans with serious risks of increased zoonotic diseases. The loss of healthy soils also leads to the intensification of climate change as healthy land is the largest carbon sink in the world. Without a change in course, the situation will only get worse. By 2050, global crop yields are expected to decline by 10 percent, and in some cases the reduction could reach 50 percent. It is estimated that this will lead to a sharp increase of about 30 percent in global food prices.
And since more than half of the world's GDP depends on land resources, millions of farmers risk falling into poverty if arable land is lost, with serious consequences for migration," he said.
And these people will need answers, they will have to be given shelter and all the means to have a dignified life. Climate displaced people are often not to blame for their condition, they are just suffering what they cannot control because it is much bigger than them.
When the climate is unbearable there is nothing left to do but run away, even if trying to find fortune elsewhere is not easy. Often these people are not accepted, we can’t understand that we are the cause of climate change that has forced to abandon everything. By dint of not caring about the consequences of our actions on the climate, by dint of not thinking that every single waste left on the street, every single time we waste food, every time we waste water precious for us, we hurt the world we live in, we damage ourselves and future generations.
It is the environmental deterioration that causes migrations, if there were no deforestation, if there were no extreme events, if there were no devastating waves of heat and cold, if there were no fires and floods there would be no people needing to leave their homes for an uncertain future full of pitfalls. A future in which peace and stability seem impossible chimeras to reach.
In Mongolia, never such devastating and severe cold waves have forced thousands of people to crowd the capital Ulan Bator, to settle in squalid shantytowns on the outskirts of the city. And there, for young people who worked in agriculture and livestock, there is no future.
In Bangladesh, the recent years’ tremendous floods have created thousands of displaced people who seek refuge in the capital. They are forced to live in makeshift housing, without any dignity and without access to basic necessities, they are the workforce that, for little money, makes clothes and accessories sold in stores around the world at very high prices.
In Kenya, the drought of recent years has left many people in misery and the only way to try to save themselves has been to emigrate, to seek better luck and better living conditions elsewhere, embarking on one of those hope journeys, that too often end in tragedy.
